In this paper, we investigate combinatorialproperties and constructions of two recent topics of cryptographic interest, namely frameproof codes for digital ngerprinting, and trace...
The compression of still images by means of the discrete wavelet transform (DWT), adopted in the JPEG-2000 and MPEG-4 standards, is becoming more and more widespread because it yie...
A system to retrieve images using a description of the image intensity surface is presented. Gaussian derivative lters at several scales are applied to the image and low order 2D ...
